Abstract: ABSTRACT OF THE DISCLOSURE         Two pairs of solid state current path means, disclosed as transistors, are interconnected to provide an accurate dead band control circuit means.  The transistors have emitters that are intentionally mismatched in size thereby creating dissimilar current conducting characteristics for each pair of transistors.          The switching characteristics of each pair of transistors can be controlled by the areas of the emitters and thereby a dead band can be created between the two pairs of transistors which can be used as an accurate dead band control.

Abstract: METHOD AND MOLD FOR MAKING AN IMPROVED EGG CARTON          An inwardly offset surface of the cover of a carton is cut in a plane transverse to the top of the cover.  A protrusion on the bottom surface of a complementary recess in the latch flap extends through the hole to latch the carton with the protrusion being within the cover recess to prevent accidental opening of the carton.  The mold for producing the carton cuts the hole thermoforming by relative movement between a male key mounted in the male mold member and a female key mounted in the female mold member.  Both keys have flat surfaces transverse to the closing motion of the molds.  These flat surfaces are biased into engagement one with the other so that the plastic is cut in a shearing action.

Abstract: ABSTRACT OF THE DISCLOSURE A corn sorting and inspection system automatically inspects various characteristics of ears of corn positioned on an endless conveyor and moved past a series of consecutive grading and removal stations, ears of corn not having characteristics in conformance with predetermined standards set at each station are removed from the conveyor system at the end of the particular station, thereby sorting those ears of corn which meet the predetermined standards from those which are considered flawed.  The ears of corn are positioned lengthwise parallel to the direction of movement and in a single file on the endless conveyor and passed through each of the individual grading and removal sections, the ears of corn being automatically inspected for smut, short ears, unhusked ears, cob diameter and kernel damage.  Each grading and removal station grades or inspects the individual ears as they pass under or through standard L.E.D. scanners which sense certain light reflective characteristics of the ear of corn or length of time required for the ear to pass the sensing device.

Abstract: METHOD FOR LITHOGRAPHICALLY FABRICATING DEVICES            Abstract A method for lithographically fabricating devices is disclosed.  In accordance with the method, a sacrificial coating material (SCM), e.g., a resist, mixed with a fluorescent material is deposited onto a substrate and then etched.  SCM etching is monitored by subjecting the fluorescent material within the SCM to fluorescence-inducing energy, and detecting the resulting fluorescence.          Because the fluorescent material is etched away as the SCM is etched, fluorescence intensity decreases as SCM thickness is reduced.  Thus, SCM etch end point is accurately determined because etch end point corresponds to the point in time when the detected fluorescence ceases.

Abstract: INSULATED CABINET WITH INTERCHANGEABLE HEAT TRANSFER UNITS                       ABSTRACT Insulated cabinets with interchangeable heat transfer units dis-posed on the top thereof are disclosed and means for improving the air circulation both in the heat transfer units and within the enclosed cabinet. The heat transfer units may be refrigeration type units, freezer type units, heating type units, warming type units or proofing units. Each of the heat transfer units includes a rectangular opening in the bottom thereof to which is attached a duct through which heated or cooled air is forced. The duct has parallel front and rear walls and inclined side wills which taper to reduce the cross section of the air flow. The duct is a sliding fit inside a tunnel which extends vertically along the back wall of the cabinet. The tunnel is provided with two columns of louvers along its entire length through which the air from the duct flows. Air exiting the louvers is deflected by a baffle plate which extends the full width of the rear of the cabinet. The edge portions of the baffle plate are perforated. The air thus must move out forward through the louvers then laterally across the solid portion of the baffle plate before turning forward again through the perforations in the baffle plate into the interior of the cabinet. The improved air flow greatly reduces temperature differences within the cabinet when used as an oven, and the air flow over the heating elements is more uniform, reducing hot spots and thus prolonging their life.

Abstract: t MECHANISM AND METHOD FOR PRODUCING CUSHIONING DUNNAGE A cushioning dunnage producing mechanism and method wherein the mechanism utilizes one or more webs of sheet-like stock material, with the stock material being adapted to be disposed by the mechanism in generally superimposed relation and then fed into a crumpler section of tubular-like construction, to radially compress the sheet-like material into a pad-like dunnage product. The lateral edges of the stock material are caused to be rolled inwardly into generally spiral-like form, prior to passage of the stock material into the crumpler section, by a forming frame of generally triangular-like shape both in plan and in side elevation, with the nose of the forming frame being disposed closely adjacent the entranceway to the crumpler section. Meshed spur gears coacting with the crumpler section, coin or stitch the confronting portions of the rolled edges of stock material together, to hold the produced dunnage product in a pad-like configuration. The forming frame mechanism is operable to cause the central coined or stitched section of the pad-like product to be as thin a possible, while urging the stock material into the lateral pillow-like portions of the product, thereby providing greater resiliency to the pad-like product and one of lesser density.
